A Direct Stereoselective Approach to trans-2,3-Disubstituted Piperidines: Application in the Synthesis of 2-Epi-CP-99,994 and (+)-Epilupinine
摘要:
A simple synthesis of enantiomerically pure piperidine esters is described, offering a straightforward access to the trans-2,3-disubstituted piperidine skeleton which is present in a broad range of biologically active compounds.
Oxidative Catalysis Using the Stoichiometric Oxidant as a Reagent: An Efficient Strategy for Single-Electron-Transfer-Induced Tandem Anion-Radical Reactions
Oxidative single‐electrontransfer‐catalyzed tandem reactions consisting of a conjugate addition and a radical cyclization are reported, which incorporate the mandatory terminal oxidant as a functionality into the product.
